What makes for a good scoreboard: 1. Large, clear video replay board; 2. Full-time out-of-town scoreboard. Cannot switch to advertising or "let's go team" messages during the game; 3. Lineups of each team displayed at all times; 4. Misc. key information easy to find (ie. pitch count/speed; OBP of batter, etc.) Based on those criteria, a few of my favorites are: 1. Washington. I liked the layout of the board (image in this thread is a good representation), it's big and clear and you can find anything at a glance. 2. House of Evil. Credit where credit is due; the thing is HUGE and can be seen clearly everywhere, especially the affordable seats in the stratosphere. 3. Arizona. Recently upgraded the main video board. Extra credit for having the lineups and out-of-town scores posted, full-time, separate from the main board to the info is always there, even when the "Go D-Backs!!!!!" message needs to appear. 4. Kansas City. Recently upgraded, and also a giant board that can be seen from everywhere. I found the layout a little busy which was the only real drawback. 5. Target Field had a very nice video board but the out-of-town scoreboards were difficult to find and weren't "full-time." Also nice: Cincinnati, which has been upgraded since the picture in this thread was taken. St. Louis was also pretty good and gets a nod for having a board above the bullpen specifically to indicate who is warming up. Ballparks that need upgrades: Detroit, Philadelphia, Dodger Stadium. Oakland too, but I know why they haven't.
